Lisa buys a dozen apples and two oranges. Jeremy buys six apples. Oranges cost $1 each, and they spend $11 total. How could you define variables to find the cost of the apples and oranges?
Answers
Answer:
3
Step-by-step explanation:
I just answered that one on a quiz
this is because 18 apples + 2 oranges = $11
the question says each orange is $1, therefore 2 oranges are $2
$11-$2= $9
the 9$ which is remaining is spent on the 18 apples... each apple should be at equal price ..
meaning you just go $9 divided by 18= 0.5
0.5 is 50 cents
that is just a solution to the price of the apples and oranges, i’m not sure if that ‘defines the variables’ tho?? you could call apples the x value and do
x + 2 = 11
take 2 on both sides
x= 11-2
x=9
9 is the total amount spent on apples but
9/18= 0.5
since 18 is the total number of apples bought !
i don’t know if this is correct.. please check the answers to confirm my solution :) good luck!
btw it’s 18 apples
because a dozen = 12
+ Jeremy’s 6 apples:
12+6= 18!!!

What is the area of the square?A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.
Also, each vertex of the square has an angle equal to 90 degrees.
The area of the figure is the product of the length of the side.
Area of square = Side × Side
The area of a square with side x is 9. Then the area will be
Area = 4x

Answer:
m<DEF = 47°
Step-by-step explanation:
Given:
m(DEF) = 266°
Required:
m<DEF
Solution:
m<DCF = ½(m(DEF)) (Inscribed angle theorem)
Substitute
m<DCF = ½(266°)
m<DCF = 133°
Opposite angles in an inscribed quadrilateral are supplementary.
Therefore,
m<DEF = 180° - m<DCF
m<DEF = 180° - 133°
m<DEF = 47°

what is the formula for speed when speed isnt given
Answers
Step-by-step explanation:
what do you mean lf speed is not given what we have tofind
Answer:
v = d/t, perhaps.
Step-by-step explanation:
Velocity (speed) is defined as distance traveled divided by the time it takes to travel that distance.
This gives an average speed. For example, I'll be taking a trip tomorrow of about 150 miles. If it takes me 3 hours, my average speed is v = 150/3 = 50 miles per hour.
That does not mean my speed is constantly 50 miles per hour; I sometimes go slower than that (maybe even stopping for red lights!), and sometimes I'll be going faster than that.
A lot of school math problems assume a constant speed.

Answer: A=(5,2) B=(5,-1) C=(6,-1) D=(6,2)
Step-by-step explanation: part D: The x-coordinates of the translated figure are 2 more than the original x-coordinates. The y-coordinates of the translated figure are 4 less than the original y-coordinates.
Part E: A translation of two yards east involves moving 2 units in the positive x-direction. Given any initial x-coordinate, x, the algebraic expression that represents the new x-coordinate after the translation is x + 2.
Part F: A translation of four yards south involves moving 4 units in the negative y-direction. Given any initial y-coordinate, y, the algebraic expression that represents the y-coordinate after translation is y + (-4).
Part G: Combining the expressions from parts E and F, for any given initial point (x, y), the coordinates of the new point after a translation of two yards east and four yards south are (x + 2, y + (-4)).

Explain
Answers
[tex] - 4a - (8a + 1) = - 169 \\ \\ 4a + 8a + 1 = 169 \\ \\ 4a + 8a = 169 - 1 \\ \\ 12a = 169 - 1 \\ \\ 12a = 168 \\ \\ a = \frac{168}{12} \\ \\ a = 14 \\ \\ this \: was \: helping \: you[/tex]
Step-by-step explanation:
Okay so remember the BODMAS rule where u start with brackets right; Since we're proving that RHS =LHS ,we look at the side which is more complicated and solve it first.
RHS: -4a-(8a+1) =-169
-4a-8a-1=-169
-4a-8a= -169+1 ( N:B like terms)
-12a= -168
-12a/-12= -168/-12
a= 14
Then go back to the original equation and subtitute .
where u see a u put the value u calculated.
-4a-(8a+1)=-169
-4(14)-(8(14)+1)= -169
-169= -169 and u DONE!!

Use your model to predict how many pieces are in the Star Wars LEGO Death Star™ set. (It costs $499.99.)
Record your answer below. Then explain your strategy.
Answers
Using the model to predict, the number of pieces in the Star Wars LEGO Death Star™ set is:
4167 approximately.MODEL TO PREDICT.
To predict the cost of a thing or its number with previous data, in this case pieces of a set, you can follow the next steps:
1. Make a graph with that has the price in the y-axis, and the number of pieces in the x-axis (Picture 1).
2. Add all the data you can use for this exercise, for example, the small LEGO set that bought Mackenzie in $5.49 with 43 pieces (Picture 2).
3. You must draw the trend line to define the formula of the model (Picture 3).
4. The formula of the model is y = kx, where k is the value of the trend line (0.12 approximately given by the graph), with this the formula would be y = 0.12x.
5. As you know, the y variable is the price and the x variable is the number of pieces, how you have the price given in the exercise ($499.99), you can solve x, replace y value and calculate the number of pieces:
y = 0.12x
x = y / 0.12
x = 499.99 / 0.12
x = 4166.58
x ≅ 4167 pieces.
As you can see, the number of pieces calculated with the formula from the model is 4167 pieces.
